How can I add authorization header to the request in WCF?
提问by umais
I'm working on a Windows Form application and there's a WCF service that needs to be called. I need to add a header (authorization - custom) to the request before it's sent to the service. I have a custom inspector class as well. I tried the following but the service is not called, somehow, and it returns an exception.
我正在处理一个 Windows 窗体应用程序，并且需要调用一个 WCF 服务。在将请求发送到服务之前，我需要向请求添加标头（授权 - 自定义）。我也有一个自定义检查器类。我尝试了以下操作，但以某种方式没有调用该服务，并且它返回一个异常。
public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
MessageHeader header = MessageHeader.CreateHeader("Authorization", "", "Basic Y19udGk6Q29udGlfQjNTVA==");
OperationContext.Current.OutgoingMessageHeaders.Add(header);
HttpRequestMessageProperty httpRequestProperty = new HttpRequestMessageProperty();
httpRequestProperty.Headers.Add("Authorization", "Basic Y19udGk6Q29udGlfQjNTVA==");
httpRequestProperty.Headers.Add(HttpRequestHeader.UserAgent, "Continental");
OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;
sentMessages.Add(request.ToString());
return null;
}
I also tried simplest way like this one:
我也尝试过像这样的最简单的方法：
MessageHeader header = MessageHeader.CreateHeader("Authorization", "", "Basic Y19udGk6Q29udGlfQjNTVA==");
request.Headers.Add(header);
but it's the same, authorization header is added but it does not reach the service, how can I know what header is received by the service? I used SOAP UI and service responds well when I add such a header manually in the request (before running).
但它是一样的，添加了授权标头但它没有到达服务，我怎么知道服务收到了什么标头？当我在请求中手动添加这样的标头时（在运行之前），我使用了 SOAP UI 并且服务响应良好。

The simplest way is to add it on the client side:
最简单的方法是在客户端添加它：
using (MyServ.ServiceClient proxy = new MyServ.ServiceClient())
{
using (new System.ServiceModel.OperationContextScope(proxy.InnerChannel))
{
MessageHeader head = MessageHeader.CreateHeader("Authorization", "http://yournamespace.com/v1", data);
OperationContext.Current.OutgoingMessageHeaders.Add(head);
}
}
and retrieve it on the server side:
并在服务器端检索它：
string auth = OperationContext.Current.IncomingMessageHeaders.
GetHeader<string>("Authorization", "http://mynamespace.com/v1");
I also suggest that you check these articles:

If there's some problem with your BeforeSend method, this is how I implemented it when adding authentication to some webservice calls.
如果您的 BeforeSend 方法有问题，这就是我在向某些 Web 服务调用添加身份验证时实现它的方式。
private const string Authorization = "Authorization";
public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
object httpRequestMessageObject;
if (request.Properties.TryGetValue(
HttpRequestMessageProperty.Name, out httpRequestMessageObject))
{
var httpRequestMessage = httpRequestMessageObject as HttpRequestMessageProperty;
if (string.IsNullOrWhiteSpace(httpRequestMessage.Headers[Authorization]))
{
httpRequestMessage.Headers[Authorization] = "Basic Y19udGk6Q29udGlfQjNTVA==";
}
}
else
{
var httpRequestMessage = new HttpRequestMessageProperty();
httpRequestMessage.Headers.Add(Authorization, "Basic Y19udGk6Q29udGlfQjNTVA==");
request.Properties.Add(HttpRequestMessageProperty.Name, httpRequestMessage);
}
return null;
}

The problem with your solution is that it would add an HTTP header. What you need is a SOAP header, however. That could be done like this...
您的解决方案的问题在于它会添加一个 HTTP 标头。但是，您需要的是 SOAP 标头。可以这样做...
using(new OperationContextScope(client.InnerChannel))
{
// Add a SOAP Header to an outgoing request
MessageHeader aMessageHeader = MessageHeader.CreateHeader("UserInfo", "http://tempuri.org", userInfo);
OperationContext.Current.OutgoingMessageHeaders.Add(aMessageHeader);
}

I know this is late but I ran across this post so decided to fill this in, in case I ever need to remember this again. This worked for me:
我知道这已经晚了，但我偶然发现了这篇文章，所以决定填写它，以防我需要再次记住它。这对我有用：
Create the Message Inspector:
Public Class AuthenticationHeader Implements IClientMessageInspector Private itsUser As String Private itsPass As String Public Sub New(ByVal user As String, ByVal pass As String) itsUser = user itsPass = pass End Sub Public Sub AfterReceiveReply(ByRef reply As Message, correlationState As Object) Implements IClientMessageInspector.AfterReceiveReply Console.WriteLine("Received the following reply: '{0}'", reply.ToString()) End Sub Public Function BeforeSendRequest(ByRef request As Message, channel As IClientChannel) As Object Implements IClientMessageInspector.BeforeSendRequest Dim hrmp As HttpRequestMessageProperty = request.Properties("httpRequest") Dim encoded As String = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(itsUser + ":" + itsPass)) hrmp.Headers.Add("Authorization", "Basic " + encoded) Return request End Function End ClassWrite the Behavior:
Public Class AuthenticationHeaderBehavior Implements IEndpointBehavior Private ReadOnly itsUser As String Private ReadOnly itsPass As String Public Sub New(ByVal user As String, ByVal pass As String) MyBase.New() itsUser = user itsPass = pass End Sub Public Sub AddBindingParameters(endpoint As ServiceEndpoint, bindingParameters As BindingParameterCollection) Implements IEndpointBehavior.AddBindingParameters End Sub Public Sub ApplyClientBehavior(endpoint As ServiceEndpoint, clientRuntime As ClientRuntime) Implements IEndpointBehavior.ApplyClientBehavior clientRuntime.MessageInspectors.Add(New AuthenticationHeader(itsUser, itsPass)) End Sub Public Sub ApplyDispatchBehavior(endpoint As ServiceEndpoint, endpointDispatcher As EndpointDispatcher) Implements IEndpointBehavior.ApplyDispatchBehavior End Sub Public Sub Validate(endpoint As ServiceEndpoint) Implements IEndpointBehavior.Validate End Sub End ClassAdd it to your endpoint:
Dim binding As New WebHttpBinding(WebHttpSecurityMode.Transport) binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None ChlFactory = New WebChannelFactory(Of IMyServiceContract)(binding, New Uri(url)) ChlFactory.Endpoint.Behaviors.Add(New WebHttpBehavior()) ChlFactory.Endpoint.Behaviors.Add(New AuthenticationHeaderBehavior(user, pass)) Channel = ChlFactory.CreateChannel()
创建消息检查器：
Public Class AuthenticationHeader Implements IClientMessageInspector Private itsUser As String Private itsPass As String Public Sub New(ByVal user As String, ByVal pass As String) itsUser = user itsPass = pass End Sub Public Sub AfterReceiveReply(ByRef reply As Message, correlationState As Object) Implements IClientMessageInspector.AfterReceiveReply Console.WriteLine("Received the following reply: '{0}'", reply.ToString()) End Sub Public Function BeforeSendRequest(ByRef request As Message, channel As IClientChannel) As Object Implements IClientMessageInspector.BeforeSendRequest Dim hrmp As HttpRequestMessageProperty = request.Properties("httpRequest") Dim encoded As String = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(itsUser + ":" + itsPass)) hrmp.Headers.Add("Authorization", "Basic " + encoded) Return request End Function End Class编写行为：
Public Class AuthenticationHeaderBehavior Implements IEndpointBehavior Private ReadOnly itsUser As String Private ReadOnly itsPass As String Public Sub New(ByVal user As String, ByVal pass As String) MyBase.New() itsUser = user itsPass = pass End Sub Public Sub AddBindingParameters(endpoint As ServiceEndpoint, bindingParameters As BindingParameterCollection) Implements IEndpointBehavior.AddBindingParameters End Sub Public Sub ApplyClientBehavior(endpoint As ServiceEndpoint, clientRuntime As ClientRuntime) Implements IEndpointBehavior.ApplyClientBehavior clientRuntime.MessageInspectors.Add(New AuthenticationHeader(itsUser, itsPass)) End Sub Public Sub ApplyDispatchBehavior(endpoint As ServiceEndpoint, endpointDispatcher As EndpointDispatcher) Implements IEndpointBehavior.ApplyDispatchBehavior End Sub Public Sub Validate(endpoint As ServiceEndpoint) Implements IEndpointBehavior.Validate End Sub End Class将其添加到您的端点：
Dim binding As New WebHttpBinding(WebHttpSecurityMode.Transport) binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None ChlFactory = New WebChannelFactory(Of IMyServiceContract)(binding, New Uri(url)) ChlFactory.Endpoint.Behaviors.Add(New WebHttpBehavior()) ChlFactory.Endpoint.Behaviors.Add(New AuthenticationHeaderBehavior(user, pass)) Channel = ChlFactory.CreateChannel()
